As it’s likely that the majority of home recordists would be creating music on a computer and maybe using amp simulation (hardware or software) for guitar sounds, the pressing need would probably be for a decent vocal mic – an affordable cardioid pattern large diaphragm condenser being the obvious choice for such a job while also quite useful for a variety of other tasks like recording acoustic guitar. Audio Technica’s AT2035 is one such mic but it also has a sibling, the AT2050, that adds omni and figure-of-8 patterns for a more all-round capability that may be tempting.
